I’d like to hear from the guys who are riding 300’s. Did you wrap or ceramic coat your exhaust. Do you think it is worth the effort? I know the theory about higher exhaust temperatures in the expansion chamber but is this a real concern in the real world out in the bush? Thanks.
Do you really need to wrap a 2 stroke exhaust?

No wrap necessary unless you are really impatient. Some times the pipe will cool going down hill in pow and it will take about 1mississippi to heat back up and get that extra rev power. Some pipes might already be tuned on the low side and rich jetting or frozen carb will make them worse but the fatty and pc2 always worked well bare naked.
Agreed ... I have run an yz250 and have ran a cr500 no wrap needed. That engine could be 90 degrees and ripp[emoji106]

I ran a wrap for part of last year, it held up fine but it got annoying. It was always steaming up and smelled bad. A pipe guard is nice but not a necessity. I would choose a bare pipe over a wrap if those were my only choices.
The only advantage I can see is it might slow down the pipe cracking issue of the 500. My CR500 cracks the pipe pretty regularly, its an older Gnarly but it cracked it the first season it was on there. Reducing the cold shock might make it last better. I'm just going to have two pipes going and keep then welded up.

Maybe I will try one of those. I agree the FMF is crap it was just on the bike when I bought it.

I cracked 2 pipes on my KX5 over 3 seasons. Both at The same spot, left (if sitting on bike) side of pipe at the first big bend. Both fmf gnarly.
If I do the CR500 to KTM frame swap this season I will be in the market for a new pipe anyways. I have all the boxes of parts to do it just don't have a box of motivation right now. Actually I'm not sure its worth the effort for a snow bike vs the 500 steely frame.

Thanks can tell you this moving from a steely cr500 frame to the 2014 450sxf it was a huge change in handling and nimbleness with the new chassis... I thought the same thing as you snowbike was but was proven wrong... Take it for what it is worth... 97 to 2014 was a big jump in frame tech.

The main difference is in head tube angle.
Take the steelie and lengthen the strut rod (or tss) and lower the subframe and i bet you get 90% of the gains. ( minus the 2x4 seat, tiny tank and all the work )
I know what you mean, I rode my YZ last season almost every day, I just miss the power and lighter feel of the 500. The 2 stroke carries most of its weight low in the frame, no cams etc etc etc. In the steely frame with the LT it can get to be a handful, mostly when I'm riding it slow, when I'm ripping in 2nd or 3rd gear it makes no difference. Quite often I can grab 4th and even 5th in a climb, it just rips.

I tell you at this point I like the trees so much that I have been focusing on nimbleness and reliably at this point in riding. Now the Cr500 I had was on an 15 LT so changing to the Camso and yz250 was probably a big jump in both departments... For me it just lends itself to more smiles .... More work than some bikes to get from point a to b but man its just plain fun...

That tech is available when you phone up and order the best snowbike pipe ever built haha. Too many folks on here in the past taking ideas and selling them as their own.
But anyhow wrap is junk. Don’t bother for many reasons.
